Description

Discovered while testing Sandcastles for the 1.75 release. This appears to be an issue in the last release too.

  1. Go to the Export KML Sandcastle (https://sandcastle.cesium.com/index.html?src=Export%20KML.html)
  2. Choose "Model" and "Download"
  3. Open this KMZ in Google Earth

It fails to load with the following error:

I can open this COLLADA file successfully in Blender:

We should investigate if this is something we're incorrect/invalid in the sample model we're using here that Blender is accounting for.

Contributor guide

Research direction
Inspect the COLLADA model used in the Export KML Sandcastle and compare with Google Earth's expected format. Check if the model has invalid geometry or references that cause the loading failure.
